Got the head back from the machine shop and suspect they may have got it wrong. The valve springs have been installed nonuniform. Some have the tight end of the spring up and others down - THAT CANT BE RIGHT? I'm in my 60's but seem to recall that the tight part of the valve spring should always be at the bottom correct? PS. Head is from our D1 but that shouldn't matter as the head design is the same for the RRC. Thanks.

Are these progressive springs?? I know they have them for Dart and EQ racing heads, but a rover? If it is a uniform design spring, where the windings are the same diameter from one end to the other, is there any chance your viewing angles are different for each spring? If they are indexed randomly, it's pretty easy to get an optical illusion of sorts. And if the spring has a machined flat "bottom", I don't think they would have been able to get the retainer to seat if put in upside down. Got a picture of them?

I checked since I have some springs in my stash (3.5 Carb) and they are uniform with machined flat side same on each end. You can flip them over with no noticeable visible difference.
